The ChromeOS EC has mapped memory regions where things like temperature
sensors and fan speed are stored. Provide access to those from the
cros-ec mfd device.
Turns out struct cros_ec_device already provides a cmd_readmem callback,
which is widely used by other drivers. Why don't you just use it ?
This is only actually set by the lpc version of the cros_ec. I2C and
SPI connected ECs
Hmm - weird. I thought I saw it implemented for those, but I must have been
struck by lightning or something. Let me check with Gwendal to see how
this (ie its use from iio) is supposed to work on non-LPC systems.

emulate it. I can most certainly hook it up in the (spi,i2c) drivers,
but the implementation
for SPI and I2C needs to live somewhere. drivers/platform/chrome/cros_ec_proto.c
seemed to be a good place.
Thanks for the feedback!
Moritz
